In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. [1][2] Torsion could be defined as strain [3][4] or angular deformation, [5] and is measured by the angle a chosen section is rotated from its equilibrium position. [6] .

Torsion is a type of mechanical deformation experienced by an object when a twisting force is applied to it. In engineering, torsion is commonly observed in shafts and other cylindrical structures that are subjected to torque, resulting in angular displacement and shear stress.

Torque is a moment that twists a structure. Unlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section.

May 9, 2021 · Torsion is expressed in either the Pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is expressed in newton metres (N·m) or foot-pound force (ft·lbf).

Mar 14, 2025 · Torsion is a twisting force that affects structural components by inducing shear stress and deformation. If not managed properly, torsion can weaken buildings, bridges, and mechanical systems, leading to structural failure.

Mar 28, 2025 · Torsionally loaded shafts are among the most commonly used structures in engineering. For instance, the drive shaft of a standard rear-wheel drive automobile, depicted in Figure 1, serves primarily to transmit torsion.

Torsion • Torsion refers to the twisting of a structural member when it is loaded by couples that produce rotation about the longitudinal axis • The couples that cause the tension are called Torques, Twisting Couples or Twisting Moments

Torsion refers to the twisting of an object due to an applied torque, causing shear stress, while bending involves deformation of a structure due to an external load perpendicular to its longitudinal axis, causing tensile and compressive stresses.

• Torsion refers to the loading of a member that tends to cause it to rotate or twist • Such a load is called a torque, rotational moment, twisting moment or couple • Torsional deformation created when a torque is applied to a member, shearing stress is developed Torsion by Nur F Ariffin
